Description
TECHNICAL FIELD
[0001] The present disclosure relates to the field of home
appliances, and particularly relates to a spring bearing beam and a
frame of laundry treatment apparatus that are easily assembled.
BACKGROUND
[0002] Existing laundry treatment apparatus has various internal
structures, and the complex internal structures lead to a complex
assembly process and low assembly efficiency of workers, and
increase production costs. The existing laundry treatment apparatus
such as a washing machine or a dryer includes a frame and laundry
treatment tubs. The laundry treatment tubs include an outer tub and
an inner tub that can be rotationally disposed inside the outer
tub. An upper portion of the outer tub is hooked, by using a
suspension spring, to a spring bearing beam fixed on reinforcing
members on the frame, and a bottom portion of the outer tub is
supported by a support spring disposed on a bottom portion of the
frame.
[0003] Two sides of an existing spring bearing beam are
respectively provided with a screw hole to fix the spring bearing
beam to sheet metal members of a frame by using fasteners. First,
only one fixing structure (screw hole) is disposed on one side of
the spring bearing beam, which has poor fixation effect. Especially
in the process of transportation or violent movement of the inner
tub, the spring bearing beam is easily detached from the frame
because force is applied on the fixing structures on the two sides
of the spring bearing beam, leading to an accident. On the other
hand, the existing spring bearing beam is asymmetrically designed.
In an actual assembly process, an operator needs to adjust a
location of the spring bearing beam for assembly, and the operator
needs to adjust locations of a front side, a back side, a left
side, and a right side of the spring bearing beam, to properly
assemble the spring bearing beam. In other words, the spring
bearing beam can be fixed to reinforcing members on the frame in
only one gesture. As a result, during actual operation, an assembly
time of the operator is wasted, and the operator first needs to
recognize the gesture thereof and adjust a location of the spring
bearing beam to locate and assemble the spring bearing beam.
[0004] In view of this, the present disclosure is proposed.
SUMMARY
[0005] A technical problem to be solved by the present disclosure
is to overcome deficiency of the prior art. The present disclosure
provides a spring bearing beam. A first connection structure and a
second connection structure are respectively disposed on an upper
side and a lower side of the spring bearing beam, and the spring
bearing beam is fixedly connected with reinforcing members on a
frame of a laundry treatment apparatus by using the first
connection structure and/or the second connection structure. When
the spring bearing beam is fixed to the reinforcing members on the
frame by using both the first connection structure and the second
connection structure, the fixing effect of the spring bearing beam
is improved. When the first connection structure and the second
connection structure are symmetrically arranged in up and down
direction, a left side and a right side of the spring bearing beam
are used interchangeably, and in an actual assembly process, there
is no need to differentiate between the left side and the right
side of the spring bearing beam, and only a back side and a front
side of the bearing beam need differentiation, thereby saving time
of adjusting a location of the bearing beam in the assembly
process, and improving working efficiency.
[0006] To solve the foregoing technical problem, a basic concept of
technical solutions used in the present disclosure is as
follows:
[0007] A spring bearing beam includes a body with a strip-shape. A
first connection structure is disposed on an upper side of the
body, a second connection structure is disposed on a lower side of
the body, and the body is fixedly connected with a reinforcing
member arranged on a frame of a laundry treatment apparatus via the
first connection structure and/or the second connection
structure.
[0008] In the foregoing solution, the body may be fixedly connected
to the reinforcing member on the frame of the laundry treatment
apparatus by using the first connection structure and/or the second
connection structure. When the body is fixed to the reinforcing
member on the frame by using both the first connection structure
and the second connection structure, the fixing stability of the
spring bearing beam is improved.
[0009] Preferably, the first connection structure includes two
connection structures respectively located at two ends of the upper
side of the body, and the second connection structure includes two
connection structures that are respectively located at two ends of
the lower side of the body. The first connection structure and the
second connection structure may be a same connection structure or
different connection structures.
[0010] Preferably, the first connection structure and the second
connection structure are the same structure.
[0011] Preferably, the two connection structures of the first
connection structure on the upper part of the body and the two
connection structures of the second connection structure on the
lower part of the body are symmetrically disposed on the upper side
and the lower side of the body in up and down direction.
[0012] In the foregoing solution, when the first connection
structure and the second connection structure are symmetrically
arranged in up and down direction, a left side and a right side of
the spring bearing beam can be used interchangeably, and in an
actual assembly process, there is no need to differentiate between
the left side and the right side of the spring bearing beam, and
only a back side and a front side of the bearing beam need
differentiation, thereby saving time of adjusting a location of the
bearing beam in the assembly process, and improving working
efficiency.
[0013] Preferably, the first connection structure includes through
holes disposed on edges of the two ends of the upper side of the
body, and the upper side of the body is fixed on the reinforcing
member on the frame by fasteners through the through holes, or the
first connection structure includes contact portions, located on
edges of the two ends of the upper side of the body, in contact
with the reinforcing member on the frame, and the contact portions
are welded onto the corresponding reinforcing member; and/or [0014]
the second connection structure includes through holes disposed on
edges of the two ends of the lower side of the body, and the lower
side of the body is fixed to the reinforcing member on the frame by
fasteners through the through holes, or the second connection
structure includes contact portions, located on edges of the two
ends of the lower side of the body, in contact with the reinforcing
member on the frame, and the contact portions are welded onto the
corresponding reinforcing member.
[0015] Preferably, a first spring hooking portion is disposed on
the body in correspondence to the first connection structure, a
second spring hooking portion is disposed in correspondence to the
second connection structure, the first spring hooking portion and
the first connection structure are located on a same side of the
body, and the second spring hooking portion and the second
connection structure are located on a same side of the body.
[0016] In the foregoing solution, when the spring bearing beam is
fixed on the reinforcing member on the frame by using the first
connection structure, the first spring hooking portion is used to
hook a spring, and when the spring bearing beam is fixed on the
reinforcing member on the frame by using the second connection
structure, the second spring hooking portion is used to hook a
spring; or [0017] when the spring bearing beam is fixed to the
reinforcing member on the frame by using both the first connection
structure and the second connection structure, a spring hooking
portion corresponding to a connection structure in a higher
position in the first connection structure and the second
connection structure is used to hook a spring.
[0018] Preferably, the two spring hooking portions are
symmetrically disposed on the body in up and down direction, so
that after the spring bearing beam is fixed on the reinforcing
member on the frame, the spring hooking portion corresponding to
the first connection structure or the second connection structure
being above the other one is used to hook the spring.
[0019] In the foregoing solution, the two spring hooking portions
are symmetrically disposed in up and down direction, so that when
the first connection structure is higher than the second connection
structure, the first spring hooking portion is used to hook the
spring, and when the second connection structure is higher than the
first connection structure, the second spring hooking portion is
used to hook the spring.
[0020] Preferably, a projection portion of strip-shaped is formed
through stamping towards a side on a middle portion of the body in
a length direction of the body, the two spring hooking portions
include two notches that are longitudinally symmetrically formed on
the projection portion. And the first connection structure and the
second connection structure are respectively disposed on a planar
structure above the projection portion and a planar structure below
the projection portion on the body. Preferably, irregular
structures are formed on surfaces of side walls and a top wall of
the projection portion, wherein the irregular structures include
multiple uneven planes, and the planes transit smoothly or
non-smoothly.
[0021] In the foregoing solution, the projection portion has an
irregular structure, helping to increase strength of the spring
bearing beam. The body of the spring bearing beam is a strip-shaped
plate structure, the projection portion is formed through stamping
in the length direction of the strip-shaped structure towards the
side perpendicular to the body. The projection portion is a
strip-shaped structure located on the middle portion of the body,
so that the spring bearing beam is symmetrically arranged in up and
down direction. Therefore, the left side and the right side of the
spring bearing beam can be used interchangeably, and in the actual
assembly process, there is no need to differentiate between the
left side and the right side of the spring bearing beam, thereby
improving assembly efficiency.
[0022] Preferably, the strip-shaped projection portion includes the
side walls and the top wall, a transition between the side wall and
the top wall is unsmooth, and the two spring hooking portions
respectively include a first notch formed on the side wall on a
side of the projection portion of strip-shaped and the connected
top wall and a second notch formed on the side wall on the other
side of the projection portion of strip-shaped and the connected
top wall.
[0023] In the foregoing solution, the first spring hooking portion
includes the first notch formed on the upper side wall and the
connected top wall of the projection portion, so that the first
notch is used to hook the spring when the first connection
structure is higher than the second connection structure. Because
the notch is formed on the upper side wall of the projection
portion, a hook on an end portion of the spring is inserted into
the notch from top to bottom, and is supported by the top wall.
Similarly, the second spring hooking portion includes the second
notch formed on the lower side wall and the connected top wall of
the projection portion, wherein the first notch is not communicated
with the second notch, and the first notch and the second notch are
separated by the top wall, so that the second notch is used to hook
a spring when the second connection structure is higher than the
first connection structure. The hook on the end portion of the
spring is inserted into the second notch on the side wall of the
projection portion from top to bottom, and is supported by a
portion of the top wall between the first notch and the second
notch.
[0024] Preferably, an avoidance structure for avoiding the spring
is further disposed on the body, so that after the spring is hooked
to a spring hooking portion, there is a gap between a helical
segment of the spring and the body.
[0025] In the foregoing solution, because portions of the body on
two sides of the projection portion have planar structures, when
the spring is hooked to the spring bearing beam, an angle of
inclination between the spring and the planar structures (namely,
vertical planes) on the two sides of the projection portion is
relatively small, and the spring is easily in frictional contact
with the planar portions, and noise is easily generated, which does
not facilitate hooking stability of the spring. Therefore, in the
present disclosure, the avoidance structure is disposed to prevent
friction between the planar portions and the spring, and stably
hook the spring to the spring bearing beam.
[0026] Preferably, the avoidance structure is two concave portions
symmetrical that are formed through local curving-in on upper and
lower sides of a surface of the body facing to the spring, and
there is a gap between the spring and a surface of the concave
portion located at the lower side of the bearing beam when the
spring is hooked to the spring hooking portion.
[0027] Preferably, the two concave portions are respectively
located on the planar structure of the body above the projection
portion and the planar structure of the body below the projection
portion, and extend from the projection portion to edges of the
body. The extension directions of the two concave portions are
perpendicular to the projection portion, and widths of the concave
portions are gradually increased from edges of the projection
portion to the edges of the body, to prevent contact between the
helical segment of the spring and the body.
[0028] Further, the top wall of the projection portion has
different heights, and locations of the first spring hooking
portion and the second spring hooking portion on the top wall are
higher than adjacent portions on the top wall. From the view of a
cross-section of the spring bearing beam, a ratio of a width of the
projection portion to a width of the planar structure above or
below the projection portion is 1:2 to 3:2. Preferably, the ratio
of the width of the projection portion to the width of the planar
structure above or below the projection portion is 1:1. The
inventors have proven through a large quantity of experiments that
when the ratio of the width of the projection portion to the width
of the planar structure above or below the projection portion is
1:2 to 3:2, the spring bearing beam has relatively good bearing
strength, and meets a safety condition.
[0029] Another objective of the present disclosure is to provide a
frame of a laundry treatment apparatus. The frame includes the
foregoing spring bearing beam.
[0030] Compared with the prior art, after the foregoing technical
solutions are used, the present disclosure has the following
beneficial effects:
[0031] 1. The spring bearing beam in the present disclosure
includes the body of strip-shaped, the first connection structure
is disposed on the upper side of the body, the second connection
structure is disposed on the lower side of the body, and the body
is fixedly connected to the reinforcing member on the frame of the
laundry treatment apparatus by using the first connection structure
and/or the second connection structure. Preferably, the first
connection structure and the second connection structure are
symmetrically disposed on the upper side and the lower side of the
body. The left side and the right side of the spring bearing beam
are used interchangeably, and in the actual assembly process, there
is no need to differentiate between the left side and the right
side of the spring bearing beam, and only the back side and the
front side of the bearing beam need differentiation, thereby saving
time of adjusting the location of the bearing beam in the assembly
process, and improving working efficiency.
[0032] 2. In the present disclosure, the projection portion of
strip-shaped is formed through stamping towards the side on the
middle portion of the body in the length direction of the body. The
two spring hooking portions include two notches that are formed on
the projection portion up and down symmetrically, and the first
connection structure and the second connection structure are
respectively disposed on the planar structure above the projection
portion and the planar structure below the projection portion on
the body. Preferably, the irregular structures are formed on the
surfaces of the side walls and the top wall of the projection
portion. The irregular structure includes multiple uneven planes,
and the planes transit smoothly or non-smoothly. The projection
portion has the irregular structure, helping to increase strength
of the spring bearing beam. The body of the spring bearing beam is
the strip-shaped plate structure, the projection portion is formed
through stamping in the length direction of the strip-shaped
structure towards the side perpendicular to the body. The
projection portion is the strip-shaped structure located on the
middle portion of the body, so that the spring bearing beam is
symmetrical up and down. Therefore, the left side and the right
side of the spring bearing beam can be used interchangeably, and in
the actual assembly process, there is no need to differentiate
between the left side and the right side of the spring bearing
beam, thereby improving assembly efficiency.
[0033] 3. In the present disclosure, the avoidance structures for
accommodating the spring are further disposed on the body of the
spring bearing beam, so that after the spring is hooked to the
spring hooking portion, there is a gap between the helical segment
of the spring and the body. Because the portions of the body on the
two sides of the projection portion are the planar structures, when
the spring is hooked to the spring bearing beam, an angle of
inclination between the spring and the planar structures (namely,
the vertical planes) on the two sides of the projection portion is
relatively small, the spring is easily in frictional contact with
the planar portions, and noise is easily generated, which does not
facilitate hooking stability of the spring. Therefore, in the
present disclosure, the avoidance structures are disposed, to
prevent friction between the planar portions and the spring, and
stably hook the spring to the spring bearing beam. The avoidance
structures are two symmetrical concave portions that are formed
through local curving-in on the upper and lower sides of the
surface facing to the spring on the body, and there is a gap
between the spring and the surface of the concave portion located
on the lower side of the bearing beam when the spring is hooked to
the spring hooking portion. The two concave portions are
respectively located on the planar structure of the body above the
projection portion and the planar structure of the body below the
projection portion. The two concave portions extend from the
projection portion to the edges of the body. The extension
directions are perpendicular to the projection portion, and the
widths of the concave portions are gradually increased from the
edges of the projection portion to the edges of the body, to
prevent contact between the helical segment of the spring and the
body.

implementations of the present disclosure with reference to the

[0051] As shown in FIG. 1 to FIG. 5, this embodiment provides a
spring bearing beam 2, used in laundry treatment apparatus. As
shown in FIG. 5, the laundry treatment apparatus includes a frame 1
and a laundry handling tub 5 disposed inside the frame. The laundry
handling tub 5 is hooked to the spring bearing beams 2 on the frame
1 by using springs 4. The spring bearing beam 2 includes a body of
strip-shaped, a first connection structure 21 is disposed on an
upper side of the body, a second connection structure 22 is

connected to a reinforcing member on the frame 1 by using the first
connection structure 21 and/or the second connection structure
22.
[0052] In the foregoing solution, the body may be fixedly connected
to the reinforcing member on the frame 1 by using the first
connection structure 21 and/or the second connection structure 22.
When the body is fixed to the reinforcing members on the frame 1 by
using both the first connection structure 21 and the second
connection structure 22, the fixing stability of the spring bearing
beam is improved.
[0053] Preferably, the first connection structure 21 includes two
connection structures respectively located at two ends of the upper
side of the body, and the second connection structure 22 includes
two connection structures that are respectively located at two ends
of the lower side of the body. The first connection structure 21
and the second connection structure 22 may be a same connection
structure or different connection structures.
[0054] Preferably, the first connection structure 21 and the second
connection structure 22 are the same structure.
[0055] Preferably, the two connection structures of the first
connection structure 21 and the two connection structures of the
second connection structure 22 are disposed on the upper side and
the lower side of the body up and down symmetrically.
[0056] In the foregoing solution, when the first connection
structure 21 and the second connection structure 22 are arranged up
and down symmetrically, a left side and a right side of the spring
bearing beam 2 can be used interchangeably, and in an actual
assembly process, there is no need to differentiate between the
left side and the right side of the spring bearing beam 2, and only
a back side and a front side of the bearing beam need
differentiation, thereby saving time of adjusting a location of the
bearing beam in the assembly process, and improving working
efficiency.
[0057] Preferably, the first connection structure 21 includes
through holes disposed on edges of the two ends of the upper side
of the body, and the upper side of the body is fixed to the
reinforcing members on the frame 1 by fasteners through the through
holes, or the first connection structure 21 includes contact
portions, located on edges of the two ends of the upper side of the
body, in contact with the reinforcing members on the frame 1, and
the contact portions are welded onto the corresponding reinforcing
members; and/or [0058] the second connection structure 22 includes
through holes disposed on edges of the two ends of the lower side
of the body, and the lower side of the body is fixed to the
reinforcing members on the frame 1 by fasteners through the through
holes, or the second connection structure 22 includes contact
portions, located on edges of the two ends of the lower side of the
body, in contact with the reinforcing members on the frame 1, and
the contact portions are welded onto the corresponding reinforcing
members.
[0059] Preferably, a first spring hooking portion 23 is disposed on
the body in correspondence to the first connection structure 21, a
second spring hooking portion 24 is disposed in correspondence to
the second connection structure 22, the first spring hooking
portion 23 and the first connection structure 21 are located on a
same side of the body, and the second spring hooking portion 24 and
the second connection structure 22 are located on a same side of
the body.
[0060] In the foregoing solution, when the spring bearing beam 2 is
fixed to the reinforcing members on the frame 1 by using the first
connection structure 21, the first spring hooking portion 23 is
used to hook the spring 4, and when the spring bearing beam 2 is
fixed to the reinforcing members on the frame 1 by using the second
connection structure 22, the second spring hooking portion 24 is
used to hook the spring 4; or [0061] when the spring bearing beam 2
is fixed to the reinforcing members on the frame 1 by using both
the first connection structure 21 and the second connection
structure 22, a spring hooking portion corresponding to a
connection structure in a higher position in the first connection
structure and the second connection structure is used to hook the
spring 4.
[0062] Preferably, the two spring hooking portions are disposed on
the body up and down symmetrically, so that after the spring
bearing beam 2 is fixed to the reinforcing members on the frame 1,
the spring hooking portion corresponding to the higher connection
structure in the first connection structure 21 and the second
connection structure 22 is used to hook the spring 4.
[0063] In the foregoing solution, the two spring hooking portions
are disposed up and down symmetrically, so that when the first
connection structure 21 is higher than the second connection
structure 22, the first spring hooking portion 23 is used to hook
the spring 4, and when the second connection structure 22 is higher
than the first connection structure 21, the second spring hooking
portion 24 is used to hook the spring 4.
[0064] Preferably, a projection portion 25 of strip-shaped is
formed through stamping towards a side on a middle portion of the
body in a length direction of the body, the two spring hooking
portions include two notches that are longitudinally symmetrically
formed on the projection portion 25. And the first connection
structure 21 and the second connection structure 22 are
respectively disposed on a planar structure above the projection
portion 25 and a planar structure below the projection portion 25
on the body, referring to a reference numeral 26 in the figure.
Preferably, irregular structures are formed on surfaces of side
walls 27 and a top wall 28 of the projection portion 25, wherein
the irregular structures include multiple uneven planes, and the
planes transit smoothly or non-smoothly.
[0065] In the foregoing solution, the projection portion 25 has an
irregular structure, helping to increase strength of the spring
bearing beam 2. The body of the spring bearing beam 2 is a
strip-shaped plate structure, the projection portion 25 is formed
through stamping in the length direction of the strip-shaped
structure towards a side perpendicular to the body. The projection
portion 25 is a strip-shaped structure located on a middle portion
of the body, so that the spring bearing beam 2 is symmetrical up
and down. Therefore, the left side and the right side of the spring
bearing beam can be used interchangeably, and in the actual
assembly process, there is no need to differentiate between the
left side and the right side of the spring bearing beam, thereby
improving assembly efficiency.
[0066] Preferably, the projection portion 25 of strip-shaped
includes the side walls 27 and the top wall 28, the side walls 27
and the top wall 28 do not transit smoothly, and the two spring
hooking portions include a first notch formed on a side wall 27 on
a side of the projection portion 25 of strip-shaped and the
connected top wall 28 and a second notch formed on a side wall of
the other side of the projection portion 25 of strip-shaped and the
connected top wall 28.
[0067] In the foregoing solution, the first spring hooking portion
23 includes the first notch formed on the upper side wall and the
connected top wall 28 of the projection portion 25, so that the
first notch is used to hook spring 4 when the first connection
structure 21 is higher than the second connection structure 22.
Because the notch is formed on the upper side wall of the
projection portion 25, a hook on an end portion of the spring 4 is
inserted into the notch from top to bottom, and is supported by the
top wall 28. Similarly, the second spring hooking portion 24
includes the second notch formed on the lower side wall and the
connected top wall 28 of the projection portion 25, wherein the
first notch is not communicated with the second notch, and the
first notch and the second notch are separated by the top wall 28,
so that the second notch is used to hook the spring 4 when the
second connection structure 22 is higher than the first connection
structure 21. The hook on the end portion of the spring 4 is
inserted into the second notch on the side wall of the projection
portion 25 from top to bottom, and is supported by a portion of the
top wall 28 between the first notch and the second notch.
[0068] Preferably, an avoidance structure used to avoid the spring
4 is further disposed on the body, so that after the spring 4 is
hooked to a spring hooking portion, there is a gap between a
helical segment of the spring and the body.
[0069] In the foregoing solution, because portions of the body on
two sides of the projection portion 25 have planar structures 26,
when the spring 4 is hooked to the spring bearing beam, an angle of
inclination between the spring 4 and the planar structures 26
(namely, vertical planes) on the two sides of the projection
portion 25 is relatively small, and the spring is easily in
frictional contact with the planar portions, and noise is easily
generated, which does not facilitate hooking stability of the
spring 4. Therefore, in the present disclosure, the avoidance
structure is disposed, to prevent friction between the planar
portions and the spring 4, and stably hook the spring 4 to the
spring bearing beam.
[0070] Preferably, the avoidance structure is two concave portions
261 symmetrical that are formed through local curving-in on upper
and lower sides of a surface of the body facing to the spring 4,
and there is a gap between the spring 4 and a surface of the
concave portion 261 located at the lower side of the bearing beam
when the spring 4 is hooked to the spring hooking portion.
[0071] Preferably, the two concave portions 261 are respectively
located on the planar structure 26 of the body above the projection
portion 25 and the planar structure 26 of the body below the
projection portion 25, the concave portions extend from the
projection portion to edges of the body. The extension directions
of the two concave portions are perpendicular to the projection
portion, and widths of the concave portions 261 are gradually
increased from edges of the projection portion to the edges of the
body, to prevent contact between the helical segment of the spring
4 and the body.
[0072] Preferably, the two concave portions 261 and the two spring
hooking portions are disposed on a same straight line perpendicular
to the length direction of the body, and the four parts are
symmetrically arranged up, down, left and right.
[0073] Preferably, the reinforcing member of the frame 1 of the
laundry treatment apparatus includes four vertically positioned
sheet metal members 11, the first connection structure 21 above the
projection portion 25 and the second connection structure 22 below
the projection portion 25 that are on the two ends of the body of
the spring bearing beam 2 are separately fixed with two sheet metal
members 11 on one side of the frame 1. A left connection structure
of the first connection structure 21 on an upper-left side of the
body and a left connection structure of the second connection
structure 22 on a lower-left side of the body are fixed with one
sheet metal member on the frame 1, and a right connection structure
of the first connection structure 21 on an upper-right side of the
body and a right connection structure of the second connection
structure 22 on a lower-right side of the body are fixed with
another sheet metal member on the frame 1.
[0074] Further, the top wall 28 of the projection portion has
different heights, and locations of the first spring hooking
portion 23 and the second spring hooking portion 24 on the top wall
28 are higher than adjacent portions on the top wall 28. From the
view of a cross-section of the spring bearing beam 2, a ratio of a
width of the projection portion to a width of the planar structure
26 above or below the projection portion is 1:2 to 3:2. Preferably,
the ratio of the width of the projection portion to the width of
the planar structure 26 above or below the projection portion is
1:1. The inventors have proven through a large quantity of
experiments that when the ratio of the width of the projection
portion to the width of the planar structure 26 above or below the
projection portion is 1:2 to 3:2, the spring bearing beam 2 has
relatively good bearing strength, and meets a safety condition.
[0075] In the present disclosure, the spring hooking portions are
two notches formed on the projection portion. Preferably, a spring
holder 3 is mounted on the notch, thereby improving an effect of
hooking the spring 4. The spring holder 3 is a "U"-shaped
structure. An insertion groove 31 is formed on an outer periphery
of the U-shaped structure, for insertion fit with the notches, and
a U-shaped groove in a middle portion of the U-shaped structure is
used to fit with the hook of the spring 4. In the present
disclosure, one spring bearing beam 2 corresponds to one spring
holder 3, and the spring holder 3 is mounted on a higher spring
hooking portion of the spring bearing beam.
[0076] Further, a first laundry handling tub and a second laundry
handling tub are vertically disposed up and down in the frame. A
mounting platform is mounted between the first laundry handling tub
and the second laundry handling tub in the frame, and is used to
mount drying equipment of each laundry handling tub, and other
fittings, as shown in FIG. 1. The spring bearing beam is mounted in
a location on the frame corresponding to the mounting platform, so
that the mounting table can be fixedly connected to the spring
bearing beam by using fasteners.

frame of laundry treatment apparatus. The frame includes a
horizontally-disposed square base 106, a vertical beam extending
vertically upwards is disposed on each of four end corners of the
base 106. And avoidance portions 114 bent towards a center of the
base 106 of a washing machine are correspondingly disposed on two
vertical beams on a same side, to form avoidance space 119 for
mounting a curved side wall of a housing of the laundry treatment
apparatus.
[0078] The avoidance portion is formed by setting two parallel
portions inside and outside on the vertical beam of the frame and
connecting them through an inclined portion, so that an inwardly
curved flange structure is formed on the frame, to form the
avoidance space for avoiding a curved bent portion disposed on the
housing of the laundry treatment apparatus, and the housing of the

wall of the housing after avoiding, through the avoidance space,
the bent portion disposed on the side wall of the housing, to
ensure that the vertical beams and a front plate are mounted
stably, and avoid outward projection of the side wall of the
housing of the laundry treatment apparatus, thereby reducing a size
of an entire machine, and improving assembly stability.
[0080] In this embodiment, the first vertical portion 115 is
disposed further away from a center line of the base 106 relative
to the second vertical portion 117. Preferably, the first vertical
portion 115 and the second vertical portion 117 are parallel to
each other, and extend in a direction of a vertical line.

height are respectively disposed on two vertical beams on a same
side, and the avoidance portions 114 are symmetrically disposed on
the two vertical beams with respect to a vertical left-right
halving plane of the base 106, to ensure that the avoidance
portions 114 are disposed at the same height, and therefore,
effectively avoid a bent portion 118 on a side plate of the
housing.
[0082] In this embodiment, the avoidance portion 114 is disposed on
a top, and/or a bottom, and/or a middle portion of the vertical
beam, so that avoidance portion is applied to a technical solution
in which the inwardly bent portion 118 is disposed on any one of or
a combination of a top portion, a middle portion, and a bottom
portion of the side wall of the housing of the laundry treatment
apparatus.
[0083] As shown in FIG. 9 and FIG. 10, in this embodiment, the bent
portion 118 matched with the avoidance portion 114 is disposed on
the side plate of the laundry treatment apparatus. The bent portion
118 gradually inclines and is bent from bottom to top in a
direction from the common side wall of the two vertical beams to
the opposite side wall. A lower end of the bent portion 118 is
correspondingly in contact with the first vertical portion 115, and
an upper end correspondingly abuts against the second vertical
portion 117.
[0084] In this embodiment, the bent portion 118 is disposed on a
top end of a front side plate 113 of the laundry treatment
apparatus, the lower end of the bent portion 118 is at a same
height as lower ends of inclined portions 116 disposed on two
vertical beams in the front of the frame. The upper end of the bent
portion 118 exceeds or is flush with top ends of the vertical
beams, so that a rear side of the bent portion 118 abuts against
and is fixedly connected with the top ends of the vertical
beams.
[0085] As shown in FIG. 9 and FIG. 10, in this embodiment, the rear
side of a body of the front side plate 113 is correspondingly fit
with and fixedly connected with the first vertical portion 115 on
lower portions of the two vertical beams in the front of the frame,
there is a gap between the bent portion 118 disposed a top portion
of the front side plate 113 and inclined portions 116 disposed on
upper portions of the two vertical beams in the front of the frame
to form avoidance space 119. And a rear side of an upper portion of
the bent portion 118 abuts against and is fixedly connected with
the second vertical portion 117 disposed on top portions of the two
vertical beams in the front of the frame.
[0086] Certainly, in this embodiment, the avoidance portions may
also be disposed on two vertical beams on a left side, a right
side, and a rear side of the frame, so that the avoidance portions
are applied to different models of laundry treatment apparatus.

[0100] Preferably, a flange horizontally bent towards a rear side
of the frame is disposed on an upper side edge of the upper
horizontal reinforcing member 101, and the flange covers at least
top ends of the front vertical beams, so that the upper horizontal
reinforcing member 101 is correspondingly fit with and fixedly
connected with the top end surfaces of the front-left vertical beam
102 and the front-right vertical beam 104, thereby further
improving fixing strength between the upper horizontal reinforcing
member 101 and the vertical beams, and effectively improving
support stability of the frame.
[0101] In this embodiment, the frame further includes an upper-left
horizontal reinforcing member and an upper-right horizontal
reinforcing member. The top ends of the front-left vertical beam
and the front-right vertical beam are respectively fixedly
connected with the front ends of the upper-left horizontal
reinforcing member and the upper-right horizontal reinforcing
member, the upper-left horizontal reinforcing member and the left
horizontal reinforcing member are located on a same vertical plane,
the upper-right horizontal reinforcing member and the right
horizontal reinforcing member are located on a same vertical plane,
and rear ends of the left horizontal reinforcing member and the
right horizontal reinforcing member are separately connected with
the rear fixing plate of the first laundry handling tub, so that
the entire frame forms an entire frame structure, and implement
effective support and mounting fixing on a platform at the top of a
washer (not shown in the drawings). Preferably, the upper-left
horizontal reinforcing member and the upper-right horizontal
reinforcing member are tightly mounted with the front vertical
beams of the frame after being pre-assembled with the rear fixing
plate of the first laundry handling tub, to simplify an assembly
process and improve an assembly speed of the frame.
Embodiment 4
